Okay, so you bought a SE Xperia Mini and you have overheating issues with the phone. This is a known issue, but there is no fix in the latest update by Sony. I’ve read they have a calibration fix at the authorized service center, but on visiting they asked me to wait for a week. Sorry I love my phone and can’t stay away from it for a week because I didn't have a backup at that moment. So here’s how I did it myself with the help of a small script from XDA.
Why do the Capacitive Buttons get Triggered Automatically?
The back and menu buttons get automatically triggered due to overheating and the sensitivity of the buttons.
The buttons are extra sensitive so they get triggered automatically when the phone gets heated when you connect the phone to a charger, computer, Wi-Fi, when calling etc.
